Window Wall Major Cost Factors

Window walls are made of custom, floor-to-ceiling windows, so the cost range is big—between $700 and $1,600. Below are the major price factors.

  • Glass type: Some types of glass are more energy-efficient and durable, which increases the price.
  • Labor: Professional glaziers typically charge per hour. Labor costs vary by location.
  • Permits: Your window wall project may need a permit depending on your wall size, type, and location.
  • Structural engineer: You may need to hire a structural engineer to ensure your window wall is stable and safe. This can add thousands of dollars to the total cost but is well worth the investment.

Glass Type

Homeowners can choose from various types of glass. This can significantly change your project price. Here are some examples of window wall glass types.

Cost by Glass Type

Single-pane glass$50–$100
Double-pane glass$100–$300
Triple-pane glass$300–$1,000
Low-e glass$300–$1,000
Laminated glass$10–$20 per square foot
Tempered glass$12–$14 per square foot

Labor Cost

You’ll need to hire a licensed and insured glazier. A glazier specializes in installing and working with different types of glass. Glaziers charge $35 to $150 per hour depending on your location, the project’s scope, and the glazier’s experience level.

Permit Cost

You may need a building permit depending on your window wall project, location, and local rules. Removing brick or drywall often requires a permit. It will cost $150 to $2,000 depending on your municipality. Ask your glazier about permits before your project begins.

Cost to Hire a Structural Engineer

If your walls need extra structural support, you may need to hire a structural engineer to ensure your glass walls are stable and safe. Most structural engineers charge per project at a rate of $300 to $5,000. A large project may require an inspection, which adds another $500.

How to Reduce Window Wall Costs

Window wall installation is expensive, but it’s well worth the investment. Still, there are a few steps you can take to help reduce your window installation cost.


Professional vs. DIY Window Walls

Window wall installation is an advanced project and should only be done by a professional glazier. A glass wall provides structural support to your home. A small mistake could put cracks in the wall or compromise the glass and the home’s structural integrity. This could lead to a dangerous situation for you and your family.

If the wall doesn’t support the home’s weight, a pro will need to frame it to ensure a tight fit. Any spaces between the frame and wall could result in higher energy bills. A glazier will also make sure the track doesn’t warp and prevent the glass door or sliding doors from opening or closing. Only a structural engineer and a glazier are capable of completing this job safely and correctly while following local building codes.

Professional Window Wall Installation

Hiring a professional window wall installer will save you time and money while ensuring your and your family’s safety. They’ll also be able to manage all project aspects, such as selecting materials and acquiring building permits. Some glaziers offer installation warranties to guarantee their work.

Before beginning the project, you’ll meet with the glazier to discuss your needs, look over home blueprints, and determine if you need to hire a structural engineer. You’ll also review the project timeline. The glazier will then order all necessary materials, get the required permits, and remove any existing glass.

Next, the glazier will measure and prepare the opening and install the frame and glass panels. After, they’ll check that it’s properly fitted and the windows open, close, and lock smoothly. Once the window wall is sealed and weatherproofed, they’ll test for any potential leaks and drafts. Once the glazier finishes the interior and exterior surfaces around the window wall, the job is complete.

Our Recommendation

Whether you’re looking for more natural light or improved views of the outdoors, window walls can give your home the perfect high-end look. However, a window wall is expensive, especially if you opt for energy-efficient windows. Adding extra structural support can add thousands of dollars to the final price tag.

The results of this project are stunning, but don’t attempt to do the installation yourself. We recommend getting multiple quotes from the best window companies in your area.


FAQ About Window Walls

Are window walls more expensive than regular walls?

Yes, window walls are more expensive than regular walls due to the cost of glass. However, window walls offer several advantages, such as natural light, which make them worth the investment.

What is the difference between a window wall and a curtain wall?

Window walls are built one floor at a time and are supported by slabs above and below, while curtain walls are structurally independent. Curtain walls aren’t load-bearing, which means they can’t replace a load-bearing wall.

How thick should the glass in a window wall be?

The best glass depends on your specific project. The average glass wall is 3/8-inch to 3/4-inch thick. Single-pane glass can be up to 1-inch thick. Ask a professional about what type of glass is best for your project.
